Abstract
The utility model relates to a cooling water alarming device for a laminating machine vacuum pump. The cooling water alarming device is directly connected with the vacuum pump, a closed loop circuit is formed by an air switch, a pressure relay and a buzzer which are in series connection through wires, and a 220V alternating current is exerted on the closed loop circuit. Compared with the prior art, the cooling water alarming device for the laminating machine vacuum pump adopts the pressure relay which is used for detecting whether the circulating water supply of the vacuum pump is normal and can send out an alarm in time when the water supply is abnormal, so that the risk of overheat operation of the vacuum pump can be effectively eliminated, the patrol frequency of equipment maintenance men can be reduced, and the labor cost of enterprises can be lowered.
Description
Technical field
The utility model relates to a kind of warning device, especially relates to a kind of cooling water warning device for laminater vacuum pump.
Background technique
2X sliding vane rotary vacuum pump is one of basic equipment extracting gas, it with compact structure, volume is little, lightweight, ultimate vacuum is high, running is stable and the feature such as easy maintenance, is widely used in solar module encapsulation field.Solar module encapsulation at present extracts with the main supporting employing 2X rotary-vane vaccum pump of laminater the gas producing in lamination process, but because 2X sliding vane rotary vacuum pump can produce a large amount of mist of oils and the factor such as operation noise is large extracting in gas process, generally vacuum pump is separated in the industry to installation with laminater, to keep manufacturing shop internal environment.Adopt laminater to separate installation with vacuum pump, to a certain extent, keep manufacturing shop internal environment, but water-cooling tube and vacuum pump joint very easily come off (vacuum pump shakes and causes in running), when cooling water choked flow quantity not sufficient or cutout, while there is above-mentioned situation, be difficult to be found by equipment inspection personnel in time.2X sliding vane rotary vacuum pump adopts circulating water, running temperature should remain between 5-40 DEG C, vacuum pump is for a long time in overtemperature state (pump body temperature exceedes 40 DEG C), and cavity sealed device part damages and causes that degree of vacuum declines, and then after causing lamination, assembly produces bubble.In assembly, there is bubble not only to affect electrical property, more can directly affect the working life of battery component.Although numerous solar components manufacturer by the whole bag of tricks, increases the equipment personnel frequency of patrolling, periodic replacement cooling water, vacuum pump installs fixing lower margin etc. additional, to occurring that cooling water flow quantity not sufficient or cutout situation can find or avoid to occur in time.The fact shows, though above method can reduce the probability of cooling water flow quantity not sufficient or the appearance of cutout situation to a certain extent, once there is cooling water flow quantity not sufficient or cutout, is still difficult to be found by equipment inspection personnel.Blindly increase the equipment personnel frequency of patrolling, also can increase enterprises using the labor cost.
Application number is that 201210182161.8 Chinese patent discloses a kind of solar cell panel assembly laminater phonetic alarm device, Collection module is installed on laminater, and be connected with signal amplifier, A/D converter and audio alert module in turn, in audio alert module, be connected with sounder; On single-chip microcomputer, be connected with key-press module and digital display module.The utility model can detect and send audio alert by voice alarm function laminater fault in time, can extend working life and the managerial skills of laminater, but there is no special warning device for most important cooling unit.
Model utility content
The purpose of this utility model is exactly the risk that a kind of effective elimination vacuum pump overheating operation is provided in order to overcome the defect that above-mentioned prior art exists, and reduces the patrol cooling water warning device for laminater vacuum pump of the frequency of device maintenance personnel.
The purpose of this utility model can be achieved through the following technical solutions:
For a cooling water warning device for laminater vacuum pump, directly connect vacuum pump, this warning device is the closed-loop path forming through the air-break switch of wire series connection, pressure relay and buzzer, applies 220V Ac on this closed-loop path.
Described air-break switch is single-plicate air-break switch.
Described air-break switch is arranged in the electric control cubicle of laminater.
Described vacuum pump is connected with intake pipe through pressure relay, utilize the pressure of liquid to open and close the hydraulic pressure electric conversion of electrical contact, in the time that pressure reaches or drop to the setting of pressure relay, send electrical signal, make the electric elements connecting move forewarning function.
Described electric elements comprises electromagnet, motor, the time relay or magnetic clutch.
Described pressure relay is that pressure nominal value is the plunger type pressure relay of 0.6Mpa.
Described buzzer receives signal and reports to the police.
Described buzzer is arranged on the operation panel of laminater.
Compared with prior art, the utility model is owing to adopting pressure relay whether to supply water normally for detection of vacuum pump circulating water, can send in time warning supplying water when abnormal, effectively eliminates the risk of vacuum pump overheating operation, reduce the device maintenance personnel frequency of patrolling, reduce enterprises using the labor cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model is connected with vacuum pump.
In figure, 1 is that buzzer, 2 is that pressure relay, 3 is that air-break switch, 4 is that vacuum pump, 5 is that intake pipe, 6 is outlet pipe.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
A kind of cooling water warning device for laminater vacuum pump, its structure as shown in Figure 1-2, connect vacuum pump 4, this warning device is the closed-loop path forming through air-break switch 3, pressure relay 2 and the buzzer 1 of wire series connection, applies 220V Ac on this closed-loop path.The air-break switch 1 using is single-plicate air-break switch, is arranged in the electric control cubicle of laminater.The pressure relay 2 using is the plunger type pressure relay that pressure nominal value is 0.6Mpa, vacuum pump 4 is connected with intake pipe 5 through pressure relay 2, vacuum pump 4 is also connected with outlet pipe 6 in addition, utilize the pressure of liquid to open and close the hydraulic pressure electric conversion of electrical contact, in the time that pressure reaches or drop to the setting of pressure relay 2, send electrical signal, make the electric elements that connects, such as electromagnet, motor, the time relay or magnetic clutch etc. have moved forewarning function.Buzzer 1 is arranged on the operation panel of laminater, receives signal and reports to the police.
In practical operation, pressure relay 2 should be arranged on vacuum pump 4 water inlets, has the place ability output electrical signals of significant change because pressure relay 2 must be placed on pressure.If pressure relay 2 is placed on to backwater mouth place, because backwater mouth directly takes back cooling tower, pressure does not have significant change yet, so pressure relay also can not be worked.
The setting of pressure relay 2 need be adjusted according to the system pressure of circulating water.The rating value of pressure relay 2 is 0.6Mpa.Actual pressure is adjusted between 0.3Mpa-0.5Mpa.When circulating water regular supply, hydraulic pressure has slight fluctuations, adjust the hexagon socket head cap screw between plunger type pressure relay wiring terminal with inner hexagon spanner, change the setting of pressure relay, pressure relay will guarantee that false alarm does not appear in circulation normal water supply alarm system after setting up.
